Pathetic Asics Gel Nimbus 26

I bought a pair of Asics Gel Nimbus 26 for my wife (who basically use it to walk our dog) on 11 May 2024 from Sportsmans Warehouse for R3799. On 23 June 2024 after our morning walk, she realized the materials on the left big toe came loose. Immediately I reported it to Sportsmans Warehouse, obviously very furious since it's a pricy item. Their response was that it's due to my wife's foot geometry and placement during a walk/run. I almost hurst out laughing, since I myself own a pair and run 100's of kilometers per annum, whilst she walked less than 50km in hers wity no force, neglect or anything. As a consolation they offered me a "big toe hole preventor guard", yessis I just needed to keep my pose. I won't be fussing if we were at fault, but surely this is unacceptable and I either need my money back or a new pair of shoes....which my wife explicitly says she'll never trust any Asics product
